Got an odd screw, nut, bolt, washer or fastener you need to buy more of, but have no idea to how to find the right one? Amazon’s AR “Part Finder” can help. The company has rolled out a new feature on mobile that lets you point your camera at the item in question, so Amazon can scan it, measure it, then direct you to matching items from its product catalog.

The company didn’t announce the feature’s launch, but confirmed to us it was rolled out to all users a couple of weeks ago.
